Why this must be read:

Given the alien technology and the potential usefulness of both a Sentinel and an anthropologist to the Stargate team, TS/SG-1 crossovers are a natural. Not to mention they double that great slashy vibe of military hardass/brainy academic. This is a lovely set of four interconnected stories that describe a complex relationship between Jim and Blair and Jack and Daniel. Although there's a few detours, both the OTPs are together by the end. And by the final piece in the quartet, you can see how everything fits together, like an intricate puzzle, with each pair facing their own unique demons, thanks to their experiences with each other.
